Raw string and multi-line string in Python
If a string contains many characters that need to be escaped, it can be cumbersome to escape each character. To avoid this, we can prefix the string to
r indicate that this is a raw string, and the characters inside do not need to be escaped. E.g:
r'...'representation can not represent multi-line string can not contain express
If you want to represent a multi-line string, you can use the
'''Line 1 Line 2 Line 3'''
The representation of the above string is exactly the same as the following:
‘Line 1\nLine 2\nLine 3’
You can also add in front of a multi-line string
r and turn this multi-line string into a raw string :
r'''Python is created by "Guido". It is free and easy to learn. Let's start learn Python in imooc!'''
